How do you read a tape measure?
Reading a tape measure is a foundational skill, but getting it right means understanding the markings. The majority of tapes sold in Australia feature both imperial (inches) and metric (centimetres/millimetres) scales to cater to different tasks. As Total Tools (a leading Australian trade supplier) explains, you should always read from the zero point at the metal hook or tab end. The hook is loose for a reason—it compensates for its own thickness so that an inside (pushing) and outside (pulling) measurement are both accurate.
Understanding the markings: inches, feet, and metric
- Metric (mm/cm): RMIT Learning Lab (educational resource) notes that the smallest markings on the metric scale are 1 mm apart, with numbers usually written every 10 and 100 millimetres. If a reading is 15.4 cm, that’s the fourth millimetre mark after the 15 cm mark.
- Imperial (in/ft): Total Tools confirms that imperial tape measures denote inches and fractions of an inch. One inch is commonly divided into 16 smaller units called sixteenths.
- Dual-Scale: A dual-scale tape shows both metric and imperial on the same blade, allowing users to read the same length in different systems without conversion math (AIMS Industrial (specialist industrial supplier)).
How to use the hook and its end
- Measure from the zero point at the hook.
- For an inside measurement (e.g., a window frame), push the tape’s hook against one side and read from the other edge—the hook’s thickness is already accounted for.
- TightWadDIY (YouTube channel) highlights a common mistake: the hook is loose to allow for its own thickness; always measure from the same side to stay consistent.
Interpreting fractions and decimals
When a measurement falls between two centimetre marks, you’ll need to read the millimetre lines. Since 10 mm = 1 cm, a reading of 15.4 cm means you add the 4 mm to the 15 cm mark. This is the core skill for accurate metric reading. On an imperial tape, you’re looking for the closest 16th of an inch, which is the standard resolution for most timber and construction work.
What is the best tape measure in Australia?
Determining the “best” tape measure depends largely on your trade—a carpenter needs something different from a seamstress. However, in the Australian market, a few names dominate the shelves. Total Tools and Bunnings stock a wide range, with RS Online Australia (global industrial supplier) noting that metric tape measures are the global standard because decimal calculations are simpler.
Top brands: Stanley, Lufkin, Milwaukee
- Stanley: Often the default choice for its durability and price-to-performance. The Powerlock is a staple on Australasian job sites.
- Lufkin: Known for superior blade stiffness and clear, high-contrast markings, often preferred by veteran carpenters.
- Milwaukee: Gaining ground with tough, impact-resistant cases and a strong standout (blade length that extends unsupported).
Best for trades: heavy-duty 8m tapes
For professional trade use, an 8-meter tape is a sweet spot—long enough for most residential work but not as heavy as a 10-meter. A tape measure’s standout (the curve that holds the blade rigid) is critical; a longer standout means easier one-person measurements.
Price comparisons from Bunnings and Total Tools
Price is a real differentiator. While Bunnings often has the lowest price on entry-level 3m and 5m tapes, specialty tool outlets like Total Tools frequently run competitive deals on multi-packs or professional-grade single units. It’s worth checking Total Tools for sales on the brands above to get a better price per metre.
Australia is officially metric, but some automotive, machining, and heritage trades still use imperial readings (AIMS Industrial). Your choice of tape should be dictated by the markings you use most, not just the brand reputation.
The implication: For buyers who work across metric and imperial jobs, a dual-scale tape is versatile, but professionals in regulated trades must verify Class II compliance before buying.
Are cheap tape measures accurate?
It’s a fair question. You can buy a tape measure at a discount shop for a couple of dollars, but is it accurate enough? The short answer is: it can be, but you need to know its limitations. All tape measures sold must meet a certain standard. Australian Government / NMI (National Measurement Institute) guidance outlines that for length measures, only metric unit symbols are listed for the approval note in a particular class. But for general DIY, a cheap tape is often fine.
What makes a tape measure accurate?
Accuracy is defined by a legal standard (Class II or Class I), but it also depends on the edge. A tape’s hook is the primary source of error. If the hook is loose, it introduces a little play. On a high-quality tape, this play is calibrated; on a cheap one, it might not be aligned correctly.
Where cheap tapes cut costs
Cheap tapes typically cut costs in two ways: the coating (which can wear off and make it unreadable) and the locking mechanism. A weaker lock means the blade can slip back while you’re marking, which induces error. Furthermore, Athletics Australia (sporting body with facility standards) specifies that for steel tapes, accuracy is ±(0.5 mm + 0.1 mm/m). A cheap $5 tape from a retailer will not have this level of precision.
When to invest in a premium tape
If you’re installing a kitchen, building a deck, or doing any critical trim work, a premium tape is worth it. The comfort of a wide, stiff blade that stands out 2+ metres is a productivity booster.
For trade use, measures marked in both imperial and metric units may not be permitted under the cited Australian approval note for length measures (Australian Government / NMI). Check the packaging for the Class mark before buying a dual-scale tape for professional work.
Is there a tape measure on my phone?
Yes, and it’s more useful than you might think. Your smartphone uses augmented reality (AR) to measure objects by tracking the camera’s perspective. It doesn’t replace a steel tape for a scribing line, but it’s perfect for approximations.
Using the Measure app on iPhone
- Open the built-in Measure app.
- Point the camera at the object’s start point and tap +.
- Move the phone to the end point and tap the + again.
- The phone calculates the distance.
Limitation: It works for big objects on flat planes but struggles with edges, curves, and small tolerances. iPhone apps are a great “where can I buy a soft measuring tape when I don’t have one” backup but lack the precision of a physical rule.
Google Measure app for Android
Android’s equivalent is usually called “Measure” or uses a Google ARCore-based app. It functions similarly. The accuracy is impressive for a phone, usually within a few millimetres for short distances, but it degrades with distance. For a quick check, it’s excellent. For cutting a piece of cornice, it’s a gamble.
Limitations of phone measuring apps
The key limitations are the lack of a physical reference (no hook to hook onto an edge) and the inability to measure around corners. A physical tape measure is also useless for measuring your waist or chest for sewing—that’s where a soft measuring tape is required.
Where can I buy a soft measuring tape?
If you’re after a soft tape measure (often called a “soft tape” or “sewing tape”) for body measurements or fabric work, your options are broader than you might think. While a retractable steel tape is for construction, the soft tape is essential for sewing and tailoring.
Bunnings range of soft tapes
Bunnings—Australia’s biggest hardware retailer—does sell soft measuring tapes, usually in the sewing and craft section, which can be separate from the main tape measure isle. It’s a common “where can I find one” question, though stock levels vary by store. Bunnings also sells them in a pinch near the curtain and bedding section, but the sewing section is the most reliable spot.
Sewing shops and craft stores
- Spotlight: This is the go-to for soft tapes. They have a huge range of colours and lengths, and the fabric quality is higher than the hardware-store variants.
- Lincraft: Similar to Spotlight, they always have a soft tape measure in the haberdashery section.
- Kmart / Big W: These often have budget sewing kits that include a soft tape, making them a cheap buy for a single project.
Online options: eBay, Amazon, specialty stores
Online, you have a choice. RS Online Australia sells professional tools but their soft tape selection is often for engineering or fiberglass measurements (easier clean up than cloth). Amazon and eBay offer incredibly cheap tapes, often in multi-packs, but their accuracy can be questionable—on sewing fabric, a millimetre off makes a difference.
Pro tip: When buying online, look for a tape that clearly states both metric and imperial on the label. A soft tape that meets the same Class II standard as a steel rule is rare but ideal. For sewing, you don’t need the “hook” at the end—usually a plain fabric end is better.
The tape measure is a universal tool, but the “best” one is defined by its markings. In Australia, going digital or going cheap is a personal choice. For the best value, buy a $10 metric-only tape from a hardware store. For crafting, invest in a fabric tape. For professional work, pay the extra for a brand-name tape that meets Class II standards.
How to Choose the Right Tape Measure for Your Project
The table below lays out the key differences between DIY and professional requirements.
| Feature | DIY / Homeowner | Professional / Trade |
|---|---|---|
| Blade Length | 5 – 8 m | 8 – 10 m |
| Markings | Metric only (simpler) or dual (versatile) | Metric (Class II for construction) with optional imperial for heritage restoration |
| Hook | Should lie flat; magnetic hooks are a nice-to-have | Magnetic, with a true-zero hook that compensates for thickness (see Total Tools) |
| Case Material | ABS plastic (lightweight) | Steel or bi-material (rubber-grip) for drop protection |
| Lock Mechanism | Standard button; check for slop | Heavy-duty slide lock that locks at any position |
Here’s the pattern you should notice: your choice is determined by your risk of error. A DIYer can tolerate a slight inaccuracy. A tiler cannot. Australian Government / NMI (National Measurement Institute) standards state that for trade instruments, a Class II tape will give you a tolerance of a few millimetres per metre. If you’re tiling, that’s the margin of a grout line. For a cheap tape measure, that’s a typo on the box.
What this means: A professional who skimps on tape accuracy risks costly material waste; a homeowner who overspends on a Class I tape gains no practical benefit for occasional use.
Common Tape Measure Mistakes (and How to Avoid Them)
Even the best tape measure on the market will give you a wrong reading if you use it incorrectly. Here are the most common pitfalls, according to industry guidance.
The “Hook Play” Illusion
- The mistake: Holding the tape loose and assuming the hook is at the true zero.
- The fix: Press the hook against the object for an inside measurement; pull it for an outside measurement. Check out the accuracy claims from Athletics Australia; they specify an accuracy of ±(0.5 mm + 0.1 mm/m), which is wiped out if you don’t compensate for the hook.
Not Using the Correct “Side”
Tape measures have a metal hook. This hook is loose by design. If you hook it on the outside of the object and pull, the measurement is correct. If you push it against an inside corner, it’s correct. But if you use it both ways on different ends of the same object, you’re off by about 1mm—an error you won’t see but will catch up on a cut.
- Choose the right tape: steel for construction, soft for fabric, digital for long distances.
- Hook the end securely onto the starting edge.
- Pull the tape taut without over-stretching—steel tapes are calibrated for a specific tension.
- Read the measurement at eye level to avoid parallax error.
- For inside measurements, push the hook against one side and read the opposite edge.
- Always note the unit (metric or imperial) and double-check fractions.
- Test a cheap tape against a known standard before relying on it.
Upsides
- Retractable steel tapes are durable and reliable.
- Metric-only tapes eliminate conversion errors.
- Class II certification guarantees trade-quality accuracy.
Downsides
- Cheap tapes can have misaligned hooks and weak locks.
- Dual-scale tapes may not meet Australian trade standards.
- Phone apps lack the physical hook needed for precise starting.

Frequently asked questions
How accurate is a phone’s tape measure app compared to a steel tape?
Phone AR apps are typically accurate to a few millimetres over short distances but degrade with range. They lack a physical hook, so the starting point is a guess. Steel tapes with a proper hook are far more reliable for exact measurements.
What is a soft measuring tape called?
Often called a “soft tape”, “cloth tape”, “sewing tape”, or “metric tape”. It’s flexible and used for measuring curved surfaces like the body and fabric.
What is the most accurate tape measure available?
For steel tapes, look for Class I or Class II certification. In Australia, this means it’s verified against a standard. Some digital tape measures and laser tapes go beyond this, but a high-quality steel rule is hard to beat for straight lines.
How can I test if a cheap tape measure is accurate?
Compare it against a known-good steel rule. Measure a 1 m length and check the reading. Also test the hook play by measuring an inside and outside distance on the same object—a good tape will give the same result.
How do you read a tape measure in millimeters?
For a metric reading, look at the largest number (centimetres). Then count the small lines after it (each is 1 mm). “15.4 cm” means 15 cm plus 4 mm, which equals 154 mm.
Do Bunnings sell soft measuring tapes?
Yes, they do. They usually stock them in the sewing section or near the curtain install tools. It’s always worth asking a staff member, as they can be in a different aisle to the steel tapes.
